I have installed Canvas on Ubuntu Linux 18.04.
If I start the server as:
bundle exec rails server
by default it starts the development server

I am able to access Canvas on port 3000
HOWEVER
If I attempt to start the production server:
bundle exec rails server -e production
It starts fine...but am not able to open the login screen in my browser

I have tried binding the localhost IP address, the server's IP address...all to no avail.
Am not sure what the problem is...any thoughts?
